SPECIFICATION forming part of Letters Patent No. 587,585, dated August3, 1897.

Application filed September 24, 1896. Serial No. 606,826. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM F. JOHNSTON, a citizen of the United States,residing at Philadelphia, in the county of, Philadelphia 5 and State ofPennsylvania, have invented a certain new and useful Improvement inFasten ers for lVindow-Retainin g Strips, of which the following is aspecification.

My invention relates to a new and useful improvement in fastenings forretainingstrips for window-sashes, and has for its object to provide asimple, cheap, and effective device by which the retaining-strips of awindow-frame may be adjusted relative to the sashes or quickly removedfrom the windowframe in order that the sashes may be also withdrawn.

lVith these ends in View this invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claim. In order that those skilled in theart to which this invention appertains may understand how to make anduse the same, its construction and operation will now be described indetail, referring to the accompanying drawings, forming a part of thisspecification, in which- Figure 1 is a section through a portion of asash and window-frame, illustrating the application of myimprovementtothe retainingstrip thereof; Fig. 2, a similar view showing theretaining-strip just prior to being placed in position; Fig. 3, a detailface view of the window-frame and one of the escutcheonplates, by meansof which the retaining-strip is secured in place; Fig. 4, a perspectiveof the nut utilized for binding the retainin g-stri p in position, andFig. 5 is a perspective of an escutcheon having ribs formed upon itsunder side for the retaining of the nut against rotation.

In carrying out my invention I provide escutcheonplates A, which arehere shown as circular in shape and having formed therein a slot, saidslot being composed of the enlargement l3 and the contracted portion 0.

The escutcheon-plates are secured upon the face of the window-frame inproper relative position to the sash by boring a hole E and forming arecess D, by chiseling or otherwise, said recess being rectangular inshape and of a width equal to the enlargement B, so that when theescutcheonplate is secured in place by the screws I it will be flushwith the face of the sash.

The retaining-strip G has passed therethrough the screws II, (but one ofwhich is shown,) and each of these screws has run thereon a nut I ofsuch proportions that it will readily pass through the enlargement B inthe escutcheon-plate, but cannot be withdrawn through the contractedportion O of the slot, from which it will be seen that to secure thestripin place it is only'necessary to adjust the nuts upon the screws Hso that they will pass beneath the escutcheon-plates when the strip isplaced in contact with the face of the window-frame, as shown in Fig.

1, and then move the strip inward until the nuts are carried behind thereduced portion of the slot and the screws within the same.

Now it is only necessary to apply a screwdriver or other implement tothe head of the screw and turn the latter in the proper direction todraw the nut against the inner side of the escutcheon-plate, therebyfirmly binding the strip against the face of the windowframe, the nutbeing prevented from turning by the walls of the recess D.

It is obvious that at any time the retainingstrip may be adjusted to orfrom the sash by loosening the screws and after said strip has beenproperly placed retighten the same, and should at any time it bedesirable to entirely remove the strip from the window-frame this isaccomplished by backing off the screws, drawing the strips forward untilthe nuts coincide with the enlargements B in the escutcheon plates, and,finally, withdrawing 0 the nuts through said enlargements, as will bereadily understood.

One of the principal advantages of my improvement is that should awindow -sash shrink or otherwise change the retaining- 5 strips may beadjusted relative thereto, so as to prevent rattling or binding; andstill another advantage of my improvement is that should it becomenecessary to remove a win- 1 (low-sash for cleaning or painting this mayror be quickly accomplished without injuring the surface of theretaining-strips or other portion of the window-and may also be asquickly replaced by the reversed operations.

It will be seen that the cost of manufacturing my improvement is verysmall, since the escutcheon-plate may beeither cast or stamped fromsheet metal, and the screw and nut may be of standard size, and therebyprocured at small cost.

In Fig. 5 a'slight modification is shown in which ribs L are formed uponthe under side of the escutcheon, and these ribs produce a channel inwhich the nut I is adapted to fit, and is thereby prevented from turningupon its axis when the screw is revolved, instead of receiving suchguidance from the woodwork. By this arrangement the escutcheon may besecured to the window-frame by simply boring a hole of sufficientdiameter to receive the ribs and then counterboring said hole to a depthequal to the thickness of the escutcheon, and this will obviate thenecessity of chiselin g.

Having thus fully described my invention, what I claim as new and useful1s In a Window-retaining strip, screws passed through said strip, nutsrun upon the inner ends of said screws, escutcheon-plates secured to thewindow-frame, each of said plates having a slot cut therein of lesswidth than the nut, said slots having enlargements formed at one end ofa greater width than the nut, ribs formed along the edges of the. largerslots on the lower side of said plates, said ribs forming a channel inwhich the nut is adapted to fit, the ribs being such a distance apart asto engage the corners of the-nut and prevent its turning, substantiallyas described.

In testimony whereof I have hereunto affixed m y signature in thepresence of two subscribing witnesses.

XVILLIAM F. JOHNSTON.
